Accordian AjaxControlToolkit

How to insert a server control into the Accordian (AjaxToolKit control).And how to access this control while run time.

Look, here is how accordian control I am using pasting your markup

 <asp:Button ID="Button1" runat="server" Text="Change Text" /><br />    <asp:ScriptManager id="ScriptManager1" runat="server"> </asp:ScriptManager> <cc1:Accordion ID="Accordion1" runat="server"> <Panes> <cc1:AccordionPane> <Header>"Test"</Header> <Content> <asp:Textbox ID="txt" runat="server" Text="Hello"></asp:Textbox> </Content> </cc1:AccordionPane> <cc1:AccordionPane> <Header>"Test1"</Header> <Content> <asp:Textbox ID="Textbox2" runat="server" Text="Hello2"></asp:Textbox> </Content> </cc1:AccordionPane> </Panes> </cc1:Accordion
now here is what I am using to add the control in one of my pane.
 
Dim TextBox1As New TextBox TextBox1.Text ="Dynamic Test" Accordion1.Panes(0).ContentContainer.Controls.Add(TextBox1)
 
and here is the code to set the text, (you can get too).
 
CType(Accordion1.Panes(1).ContentContainer.FindControl("Textbox2"), TextBox).Text ="Dynamic Text"
